The 3rd TVLBAI workshop follows the formation of the TVLBAI Proto-Collaboration and will focus on discussing the technology and physics drivers for large-scale Atom Interferometry as well as establishing a comprehensive roadmap. The primary objectives are to bring together researchers from diverse institutions and communities, foster strategic discussions, and develop a pathway towards Funding for Terrestrial Very-Long Baseline Atom Interferometer projects expected to become operational in the mid-2030s.

In this third iteration of the TVLBAI workshop, we are gathering in Hannover, providing an opportunity to visit the newly established and now operational 10m VLBAI facility. In addition to the VLBAI visits, we are offering lab tours within the Institute of Quantum Optics and the Einstein Elevator.

Building on the success of the last two editions, this workshop will cultivate a strong sense of community among participants. It will help to establish a supportive network of experts and enthusiasts ready to advance the field of Atom interferometry from all over the world.

Astrophysics has finally entered a new era, transitioning from the multi-wavelength observation approach of the 20th century to the era of multi-messenger observations. The discovery of the binary neutron star merger event GW170817 in 2017 marked the beginning of this shift, as it was first detected through a gravitational wave and gamma-ray burst, followed by electromagnetic counterparts observed across various wavelengths, including X-ray, optical, infrared, and radio. In addition to gravitational waves, significant advancements have also been made in other multi-messenger signals, such as high-energy neutrinos and high-energy gamma rays. Traditional X-ray, optical, infrared, and radio observations are not only achieving higher sensitivities but are also making great strides in discovery science through time-domain astronomy, focusing on transient events.

The progress in multi-messenger astrophysics is unveiling the dynamic universe shaped by the evolution to black holes. Long-standing fundamental questions — such as the evolution of stars and galaxies, the mechanisms behind jet and particle acceleration, and the origin of elements — are seeing substantial advancements. At the same time, new mysteries are emerging as we deepen our understanding of the final fate of gravitational energy. These developments are also driving progress in cosmology and fundamental physics.

In this long-term workshop, we invite leading researchers from around the world to engage in in-depth discussions on the following key topics in astrophysics.

Compact star mergers and gravitational waves Gamma-ray bursts, supernovae and kilonovae Supermassive black holes, tidal disruption events and QPEs High-energy gamma-rays and neutrinos Fast radio bursts and magnetars Origin of binary black holes and neutron stars Population III stars and galaxies Related topics

During the workshop, participants stay at YITP with desks and other facilities. They can engage in extensive discussions with fellow participants in the relaxed atmosphere of Kyoto.

Multimessenger astronomy is entering a transformative era. As next-generation observatories deliver an unprecedented volume and diversity of data—across gravitational waves, electromagnetic signals, and neutrinos—the complexity of extracting meaningful insights increasingly exceeds the capacity of traditional analysis pipelines. At the same time, foundational AI models—large pre-trained networks such as transformers and diffusion models—are reshaping the landscape of scientific discovery, from natural language processing to molecular design. This two-day workshop brings these revolutions together. We will convene researchers from gravitational-wave physics, broader observational astronomy, and artificial intelligence to explore how cutting-edge machine learning can accelerate real-time detection, multimodal data integration, source classification, and astrophysical inference.

Through keynote talks and interactive panel discussions, participants will:

• Survey the current frontier of AI-driven multimessenger astronomy—what tools are proving effective, and where the next breakthroughs may arise.
• Build collaborative bridges across observatories, academic institutions, and industry research groups to foster robust, open-source development.
• Chart a roadmap toward interpretable, scalable AI systems that can adapt to rapidly evolving data streams and scientific goals.

Join us in Nashville, August 4–5, 2025, to shape the future of multimessenger astronomy in the era of foundational AI—and to help lay the groundwork for a new generation of discovery.

The upcoming workshop "Gravitational Waves meet Nuclear Astrophysics" will be held from July 7-11, 2025. The workshop will be hosted by the Nicholas and Lee Begovich Center for Gravitational-Wave Physics and Astronomy at California State University, Fullerton.

Our goal is to bring researchers from multiple fields together to understand how gravitational-wave astronomy will help us understand the dense matter equation of state and heavy-element nucleosynthesis in our universe. As gravitational wave astronomy opens new windows into the high-energy cosmos, nuclear astrophysics provides the keys to understanding the fundamental processes powering these cosmic events—from supernovae to neutron star mergers and beyond. Talks and working sessions will build connections across work in gravitational-wave rates, source populations, chemical evolution, nuclear reactions, nuclear equation of state, nucleosynthesis, hydrodynamic simulations, and transient astronomy.

As the detection of a stochastic gravitational wave background from the early universe becomes increasingly promising, signals from hypothetical first-order phase transitions are attracting growing interest. Predicting these signals often requires the solution of plasma dynamics at macroscopic scales, which, in turn, depends on the phenomena that characterize the phase transition at microscopic scales.  Therefore, various assumptions on distinctive scales and their separation are usually employed to enable concrete evaluations. 
This workshop aims to bring together researchers from both the microscopic and macroscopic communities to collaboratively address theoretical shortcomings and refine current gravitational wave spectral templates across different regimes.

1. Microscopic scales – Quantitative uncertainties affect the fundamental phase transition par
   Advancing gravitational wave predictions from cosmological first-order phase transitions parameters within minimal scenarios beyond the Standard Model, where a scalar field drives the symmetry-breaking mechanism.
2. Intermediate scales – Different approaches have been employed to describe the interactions between the scalar field and the plasma, including bubble wall dynamics and plasma viscosity. A key question is, e.g., whether the bubble wall runs away or reaches a terminal velocity.
3. Macroscopic scales – Several approximations are used to connect to large-scale phenomena during and after the phase transition, such as collisions between the bubbles, the development of turbulence, and the evolution of sound shells.
